Figure 32: Right metatarsi of selected ornithopods in proximal view. A–R: (A) Diluvicursor pickeringi; (B) NMV P186047; (C) Morrosaurus antarcticus; (D) Gasparinisaura cincosaltensis; (E) Anabisetia saldiviai; (F) Kangnasaurus coetzeei; (G) Eousdryosaurus nanohallucis; (H) Dysalotosaurus lettowvorbecki; (I) Dryosaurus altus; (J) Changchunsaurus parvus; (K) Mantellisaurus atherfieldensis; (L) Hypsilophodon foxii; (M) Tenontosaurus tilletti; (N) Cumnoria prestwichii; (O) Muttaburrasaurus langdoni; (P) Talenkauen santacrucensis; (Q) Parksosaurus warreni; and (R) Thescelosaurus assiniboiensis. Metatarsi normalised for dorsoplantar depth of metatarsal II (shaded black). Dashed lines indicate uncertain bone margins. ?, indicates location of uncertain/expected/missing metatarsal. Abbreviation: mt #, metatarsal position. For data sources, see Table S1.

Figure 36: Artist’s interpretation of the early Albian, volcaniclastic, floodplain palaeoenvironment within the Australian-Antarctic rift graben, in the region of Eric the Red West. Scene depicting two individuals of Diluvicursor pickeringi on the cutbank of a high-energy meandering river, regional floral components and distant rift margin uplands. Floral components potentially included forest trees of Araucariaceae (Agathis and Araucaria), Podocarpaceae and Cupressaceae and lower story/ground cover plants, including pteridophytes (ferns, including equisetaleans), hepatics, lycopods, cycadophytes, bennettitaleans, seed-bearing fern- or cycad-like taeniopterids and early Australian angiosperms.
